Window typically found toward the front end of some older vehicles (classic VWs, Ford trucks), triangular in shape, directs large flow of wind into the vehicle and right up the leg of one's shorts, cooling their junk.
My old F-150's air conditioning went out, but my junk's cool thanks to the ballwindow.
A threesome sexual act which requires two males and a female. It is when a man has oral sex with another man, stores the semen in his mouth, then deposits it into the girl's snatch.
With that being said in can be done with any number of people, male or female and even two people... boy and girl. That would require a tricky exchange of cum though from one person's mouth to another.
I heard becky had a " Snow Ball thrown threw the window ". Omg who throw it!? John made it but Adam threw it!" Omg so gross.
A hardo is a person who tries extremely hard at everything. Most times a hardo will try very hard at things that do not require excessive effort. For example, sports practices, gym class, etc.
Wow did you see Jack at practice today? What a hardo!
